Editing Math fab Mathonwy (section)

===Math is tricked by his nephews===
Math's nephew [[Gilfaethwy]] had become obsessed with [[Goewin]], Math's footholder. The magician [[Gwydion]] (Gilfaethwy's brother) devised a plan to make Goewin available. Gwydion told his uncle about an animal that was new to Wales, called pigs, and how he could get them from their owner, [[Pryderi]] of [[Dyfed]]. He took a band of men, including his brother, to [[Ceredigion]], where they disguised themselves as [[bard]]s to gain audience with King Pryderi.

Gwydion was a skilled ''cyfarwydd'' (storyteller) and regaled the court with his tales. Having charmed the king, he offered to trade the pigs for some horses and dogs, which he had conjured through magic. Pryderi agreed to the trade and Gwydion and his men took the pigs back home to [[Gwynedd]], but his trickery was revealed and Pryderi waged war against Gwynedd. While Math went to battle, Gilfaethwy raped Goewin.

The war ended when Gwydion killed Pryderi in single combat. Upon his return to his castle, King Math went to rest his feet in Goewin's lap, but could not, as she was no longer a virgin. He took her as his wife to save her honour, and then as punishment, banished his nephews, turning them into a breeding pair of deer for a year. He then turned them into wild boars for the next year and wolves the year after that. They had three children over the three years: [[Hyddwn]], [[Hychddwn]], and [[Bleiddwn]].
